BATTERY WARNING
WARNING: When battery is disconnected, vehicles equipped with
computers may lose memory data. When battery power is
restored, driveability problems may exist on some vehicles.
These vehicles may require a relearn procedure.
WARNING: Batteries produce flammable hydrogen gas. Keep flames and
sparks away from the battery or and explosion may occur.
Never smoke when working in the vicinity of the battery.
WARNING: When checking or servicing the battery, disconnect the
negative cable. Be careful not to cause a short circuit by
allowing metal objects to contact the battery posts and the
vehicle at the same time.
REPLACING BLOWN FUSES
CAUTION: Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical
system. Be sure to use fuse with the correct indicated
amperage rating. The use of an incorrect amperage rating fuse
may result in a dangerous electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
BRAKE HOSES
WARNING: Worn brake hoses can burst and cause brake failure. If
any sign of cracking, scuffing, or worn spots are found,
replace the brake hoses immediately.
BRAKE FLUID
WARNING: The use of incorrect fluid in the brake system may cause
damage to components. DO NOT use any fluid other than DOT-3
brake fluid. DO NOT use reclaimed fluid or fluid that has
been stored in old or open containers. It is essential that
foreign particles and other liquids are kept out of the
brake fluid reservoir.
CATALYTIC CONVERTER
CAUTION: Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible
damage to converter and vehicle.
COOLANT
CAUTION: To avoid possible damage to vehicle use only ethylene-glycol
based coolants with a mixture ratio from 50-70% anti-freeze.
DO NOT use 100% anti-freeze as it will cause the formation
of cooling system deposits.

Procedure For Programming PCM & Clearing DTCs From ABS & SRS
Modules
Connect scan tool to Data Link Connector (DLC). DLC is
located under left side of instrument panel. Using scan tool, enter
correct VIN and mileage into PCM. Using scan tool manufacturer's
instructions, clear DTCs from ABS and SRS modules.
Procedure For Updating Secret Key Data
1) Connect scan tool to Data Link Connector (DLC). DLC is
located under left side of instrument panel.
2) Go to ENGINE and then MISC menus on scan tool. Place the
SKIM in SECURED ACCESS MODE by using the appropriate Personal
Identification Number (PIN) for this vehicle. PIN may be obtained from\
the owner, vehicle's invoice, or from the manufacturer. Select UPDATE
THE SECRET KEY DATA. The data will be transferred from Smart Key
Immobilizer Module (SKIM) to the PCM, allowing the vehicle to start.
NOTE: On Ram Van and Ram Wagon, if 3 attempts are made to enter the
SECURED ACCESS MODE using the incorrect Personal
Identification Number (PIN), the SECURED ACCESS MODE will be
locked out for one hour. To exit this locked out mode, leave
ignition switch in the ON position for one hour with all
accessories turned off. It may be necessary to monitor
battery state and connect a battery charger if necessary.
ENGINE SENSORS & SWITCHES
BATTERY TEMPERATURE SENSOR
Removal & Installation
Battery temperature sensor is snapped into center of battery
tray, directly below the battery. Remove battery. Disconnect
electrical connector for battery temperature sensor. Pry battery
temperature sensor straight upward from battery tray. To install,
reverse removal procedure.
BRAKE SWITCH
NOTE: Brake switch may also be referred to as brakelight switch or
stoplight switch.
Removal (Dakota, Durango & Ram Pickup)
1) Brake switch is located near top of brake pedal. Remove
lower instrument panel cover for access to brake switch if necessary.
Disconnect electrical connector from brake switch. Depress and hold
brake pedal downward.
2) Rotate brake switch counterclockwise approximately 30
degrees so alignment tab on brake switch aligns with opening on
mounting bracket. Pull brake switch rearward from mounting bracket.
NOTE: Before installing brake switch, plunger on brake switch must
be pulled outward to fully extended position and then pushed
inward 4 detent positions to ensure proper brake switch
adjustment.
Installation
1) Pull plunger on brake switch outward to the fully extended
position. Push plunger on brake switch inward 4 detent positions. The
brake switch will click at each detent position when pushing plunger
inward.
2) Install electrical connector on brake switch. Depress
brake pedal as far as possible. Install brake switch in mounting

1) To install, reverse removal procedure. If installing small
vent tube and large fill tube on fuel tank, ensure fuel tank fittings
are clean.
2) Install disconnect fitting on fuel tank fitting until
disconnect fitting snaps onto fuel tank fitting. Pull on small vent
tube or and large fill tube to ensure disconnect fitting is locked on
fuel tank fitting. To verify proper installation of disconnect
fitting, ensure the distance between release sleeve and top of fuel
tank fitting is .50" (12.7 mm) on small vent tube or .25" (6.4 mm) o\
n
large fill tube. See Fig. 37.
3) Install fuel lines on fuel filter/fuel pressure regulator
on fuel pump module using proper procedure. See FUEL LINE DISCONNECT
FITTINGS under FUEL SYSTEM.
CAUTION: DO NOT overtighten fuel tank strap retaining nuts during
installation.
4) Tighten fuel tank strap retaining nuts to specification.
See TORQUE SPECIFICATIONS. To install remaining components, reverse
removal procedure. Start engine and check for fuel leaks.
Removal (Durango)
1) Fuel tank may be drained by removing vent hose from rear
of fuel tank, or by pumping fuel from fuel tank using the fuel pump if
fuel pump is operating. If removing vent hose from fuel tank to drain
the fuel, go to step 4). If using fuel pump to drain the fuel tank, go
to next step.
2) Disconnect fuel line from fuel rail. See FUEL LINE AT FUEL
RAIL under FUEL SYSTEM. Connect Fuel Hose (6541, 6539, 6631 or 6923)
for proper engine application at fuel line fitting on fuel rail. Place
remaining end of fuel hose in an approved gasoline container.
3) Connect scan tool to Data Link Connector (DLC). DLC is a
16-pin connector attached to bottom of driver's side of the instrument
panel, just to the right of the brake pedal. Using scan tool
manufacturer's instructions, activate the fuel pump and pump fuel from
fuel tank. Once fuel tank is empty, remove scan tool. Reinstall fuel
line on fuel rail using proper procedure. Go to step 5).
4) Release fuel pressure from fuel system. See FUEL SYSTEM
PRESSURE RELEASE. Ensure negative battery cable is disconnected.
Remove fuel tank cap to release any residual fuel tank pressure.
5) Raise and support vehicle. Remove necessary skid plates
for access to fuel tank. Disconnect vent and filler hose from rear of
fuel tank. If fuel tank was not previously drained, place drain hose
in vent hose fitting at rear of fuel tank. Drain fuel from fuel tank
into an approved gasoline container.
6) Support fuel tank with transmission jack. Remove fuel tank
strap retaining nuts. Position fuel tank straps toward outside of
vehicle. Slightly lower fuel tank. Ensure rear of fuel tank is higher
than front of fuel tank to prevent any spilling any remaining fuel in
fuel tank.
7) Disconnect fuel line from fuel filter/fuel pressure
regulator on fuel pump module using proper procedure for fuel line
disconnect fitting. See FUEL LINE DISCONNECT FITTINGS. Fuel pump
module is located on top of fuel tank. See Fig. 28. Disconnect
electrical connector at fuel pump module. Disconnect vapor line from
rollover valves on top of fuel tank and EVAP line from fuel pump
module. Lower fuel tank from vehicle.
CAUTION: DO NOT overtighten fuel tank strap retaining nuts during
installation.
Installation
1) To install, reverse removal procedure. Install fuel lines

or damage.
* Once a month, Inspect battery and clean and tighten
terminals as required.
* Once a month, check fluid levels of coolant reservoir,
brake master cylinder, power steering & transmission.
Add fluids as required.
* Once a month, check all lights and all other electrical items
for correct operation
* Once a month, Inspect and clean wiper blades as required.
* Twice a year, lubricate the external lock cylinders.
